Your Chevy thermostat’s job is to block the flow of coolant to the radiator until the engine has warmed up. No coolant flows through the engine when it is cold. When the engine reaches its operating temperature, the thermostat opens, letting the engine warm up as quickly as possible thus reducing engine wear, deposits and emissions. Protect your engine with a replacement thermostat from Eckler’s Early Chevy. Our replacement style 180 degree thermostat will perfectly replace your malfunctioning unit. Count on Eckler’s Early Chevy for all your restoration and repair parts needs.
